The cleaning solution to the problem of common CNC lathe operation

CNC lathe is a kind of integrated use of the computer technology, the active control technology, intensive measurement technology and other advanced technology of typical mechatronics product. Its control system is complex, expensive, once the attack, a lot of people because of the value of 'expensive' but to stay at a respectful distance from sb, often ask professional maintenance personnel. Both abuse human, material and financial resources and time delay. In fact, about some common operating problems, only the operator thinking, longer than the summary, pay attention to accumulation, also is not hard to find and handle problems. Now the numerical control lathe the cleaning solution to the problem of some common operation introduced to beginners reference. A, manual method, the coordinate axis movement phenomenon: not manual operation, the machine tool coordinate axis movement, not coordinate values also have no changes, M, S, T function to perform normal, no alarm system. Analyzing and processing: the fault attack system didn't attack the police, in this case, M, S, T function to perform normal, can be a preliminary judgment nc system, servo drive, etc. Should be no problem. Can therefore analyzes from the manual condition, take a closer look at the manual of the direction key input, the direction of the manual pick all normal, again carefully observe operation panel 'now bearing' page, found the manual rate, practical rate and feed rate are all zero. Identify axis do not attack the cause of the manual is a manual movement velocity is zero, adjust the percentage of feed speed from beginning, manual operation is back to normal. Second, the active work does not reach the designated position phenomenon: to position 1 tip into a known point on the workpiece, the program input method ( 互联网反歧视热线) Under the correct input related instructions, M, S instruction normal performance of machine tool coordinate axis movement, CRT screen orientation correctly, but the tip without running to the given position, no alarm system. Analyzing and processing: because the machine back to both fixed action process is normal, but didn't reach the established position. Rendering such trouble, is often associated with knife repairing to perform. Check the cutter knife repairing fulfillment situation, found that the tool function for T0103, 1 perform 3 knife cutter compensation value, cause the tip to the established functioning orientation. From the beginning in the entry way ( 互联网反歧视热线) The input T0101 that deal with this problem. Three, screw thread processing present pitch irregular phenomenon: when CNC lathe processing threads, thread section pitch is irregular, which presents the so-called teeth. Analyzing and processing: processing thread on nc lathe, the essence of the turning Angle of the X axis and Z axis interpolation between feed. Mess tooth because the X axis and Z axis feed cannot end synchronization, hysteresis cause machine tool servo system itself. GSK980T is economical nc system, the spindle speed for the open loop control, under different load, different spindle starting time, and when the spindle speed is not stable, there is also a corresponding change, the speed thread cutting beginning is measured from aspects of the main shaft bearing on a turn signal after the beginning of the encoder, so perhaps to the end of the X axis and Z axis feed not synchronization. The above problems can be treated with way to modify the program. 1, change the anchor point screw thread processing program, make it far away from the workpiece, in this way, changes the spindle speed is not safe at the end of the space, safe, tool really touch artifacts, and then start thread processing. 2, the spindle rotation instruction M03, thread processing instructions before increase G04 suspended, guarantee the spindle speed stability after beginning to thread processing. Four, processing procedure fails to fulfill the phenomenon: the numerical control lathe after startup, choose good processing program, press the active operation button, M, S, T function according to the command to perform the procedure, coordinate values show no abnormal changes, but few wear kagyu axis movement, action fails to perform the rules of procedure. Analyzing and processing: render such trouble, first think of is see if green feed speed, feed times zero, is apparent. Take a closer look at found machine interlock on the operation panel button indicator, turn off after the interlock, normal performance of the program. Five, the midway to knife phenomenon: in the process of the numerical control turning processing the non-datum collapse knife or blade wear affect the machining accuracy. ( The assumed the non-datum knife attack 3 collapse phenomenon) Analyzing and processing: this kind of problem in unskilled workers operating CNC lathe are attacks. Immediately after fault attack, we should, in turn, press the 'pause' on the operation panel, 'reset', 'program back to zero' and 'run' button, cancel the no. 3, knife knife, knife in 3 bearing heavy suitable cutting tools, processing power, measurement of workpiece diameter somewhere alpha, launch a spindle, touch it with 3 tip quietly appearance, according to the 'knife repairing' key on the operation panel, the cutting tool offset number 103 input X 'alpha'; Exit knives, stop the spindle, measurement of workpiece somewhere the steps to the interval of the workpiece origin beta, a spindle, touch it with 3 tip quietly the steps, in accordance with the 'knife repairing' key on the operation panel, the cutting tool offset number 103 Z 'beta' input. After reshipment system active calculated 3 knife knife.
